Definitions
- the invention relates to a method for the transmission of information in a universal transmission network in which functions specific to the mobile radio network and fixed network are carried out, according to the preamble of patent claim 1.
- Universal transmission networks (UMTS Universal Mobile Telecommunication System, FPLMTS Future Public Land Mobile Telecommunication System) are known from the article "Mobile communication on an expansion course" in telcom report 18 (1995), number 2, pages 52 to 55 , in which different networks and network services for personal mobile telecommunication are combined
- UMTS Universal Mobile Telecommunication System FPLMTS Future Public Land Mobile Telecommunication System
- telcom report 18 (1995)
- mobile radio subscribers whether mobile radio subscribers or fixed network subscribers - this creates universal access to a transmission network in which mobile radio network-related and fixed network-related functions are used for voice, data and image communication be performed.
- the radio subscriber station of a network subscriber can transmit the same information on a plurality of redundant transmission paths which are constructed in parallel via a radio transmission interface from the network to the radio subscriber station or from the radio subscriber station to the transmission network (macro diversity) in order to achieve the best possible transmission quality to reach.
- the information transmission via parallel redundant transmission paths is used, for example, in a radio transmission interface that uses the CDMA access method (Code Division Multiple Access) according to US Pat. No. 5,101,501.
- the redundant transmission paths can be set up and dismantled dynamically while the radio subscriber station changes its location. Even in the case of a fixed radio subscriber station, operation in this transmission mode (macro diversity) is possible over a longer period of time.
- the information which is sent by the radio subscriber station in the transmission frame on different transmission paths can be combined in the transmission network at combination points at which two transmission paths are combined in one transmission direction (uplink) to form a single transmission path and in the the other transmission direction (downlink) the individual transmission path can be divided into two transmission paths.
- the number and distribution of the combination points on network elements of the transmission network changes dynamically with the addition or removal of redundant transmission paths which can be additionally set up or removed by the radio subscriber station.
- transition point For the best possible use of the network elements of the universal transmission network, it is necessary to define a transition point at which information coded specifically for mobile radio has to be converted into information coded specifically for fixed networks. Since the transition point completes all mobile radio-specific functions, if there are several redundant transmission paths in the transmission network, conversion can only take place after all combination points. The dynamic addition and removal of redundant transmission paths results in changes in the number and distribution of the combination points and thus in the determination of the transition point in the transmission network.
- the radio subscriber station Because the radio subscriber station knows the number of parallel transmission paths that change dynamically, it enters information about the total number of combination points required in the transmission network in the transmission frame. At the combination points in the transmission network, the number of combination points which have been traversed by the incoming transmission frames is determined and information about them is also sent in the outgoing transmission frame. By knowing the total number of combination points and the number of combination points already run through at each combination point, the combination point at which the total number of
- Combination points is reached, dynamically and flexibly selected as a transition point in the transmission network.
- the method according to the invention locates the transition point for converting the information coded specifically for the mobile radio network into information coded for the fixed network, even with dynamic establishment and disassembly of redundant transmission paths (macro diversity), where a combination point combines the last two transmission paths.
- the method according to the invention also has the advantage that, in order to determine the optimal transition point when using the “Macro Diversity” transmission mode, no additional signaling effort in the form of signaling messages is required Despite the dynamic structure and reduction of redundant transmission paths on the radio transmission interface, information is selected. This ensures that the transition point is located in a network element of the transmission network so that - from the point of view of the different network levels of a network - it is as "close” as possible to the radio subscriber station.
- the information about the number of combination points already passed through is entered in the outgoing transmission frame until the total number of combination points is reached
- a combination point counter is inserted into the transmission frame to determine the number of combination points passed through, so that the current counter values of the combination point counters which are contained in the incoming transmission frames can be added to each combination point.
- the counter value resulting from the addition is increased by one in the respective combination point and the result is compared for agreement with the total number of combination points entered in the transmission frame.
- the resulting counter value of the combination point counter at a combination point reaches the value for the total number of combination points, all combinations of redundant transmission paths in the transmission network have been carried out. Therefore, the conversion of the information coded specifically for the mobile radio network into information coded for the fixed network can be carried out at this combination point or by the corresponding network element.
- the figure shows the information flow on various redundant transmission paths, which are combined at combination points in a universal transmission network.
- the network elements of a universal transmission network UNW in which both mobile radio network specifically coded information and also landline-specific coded information for personal mobile communication between network subscribers are transmitted.
- the universal transmission network UNW enables the network subscribers of different access networks, such as, for example, mobile radio networks and fixed networks, personal mobile communication independent of the respective access network.
- the transmission network UNW has as network elements a plurality of radio devices BTS, BTS 'and BTS'', a number of control devices BSC and BSC and at least one switching device LE.
- BTS radio devices
- BTS 'and BTS'' a number of control devices
- BSC control devices
- Each BTS ... radio device usually operates a radio cell that represents the smallest radio coverage area in a cellular network. By using directional antennas at one location of the radio device BTS ..., a radio cell can be divided into two or more sectored cells, which are treated by the network as ordinary radio cells.
- the control devices BSC and BSC take over the radio control functions in the transmission network, such as the radio processing functions, the management of the radio devices, the radio channel management, etc.
- Each control device BSC or BSC serves one or more radio devices BTS ... BTS ''.
- the switching device LE is connected to the control devices BSC and BSC and is arranged next to other switching devices in the switching system of the transmission network.
- the switching system takes on all the mobile network-related and fixed network-related switching functions that are involved in the set-up and clearing of call connections that relate to routing in the universal transmission network.
- the switching device LE consists of a local switching device (Local Exchange), such as is used for switching in locally limited areas of a fixed network.
- the radio subscriber station MS operates in a transmission mode in which, for a logical connection, a plurality of redundant transmission paths to the radio devices BTS ... BTS '' are set up in parallel at the same time (macro diversity). This means that the radio devices BTS ... BTS '' receive the same information, which is entered in corresponding transmission frames, via the radio transmission interface.
- the transmission frames contain information coded specifically for the mobile radio network, which can be signaling information as well as voice and data information. Because a total of m + 1 transmission paths have been set up in parallel by the radio subscriber station MS, information about the total number of m combination points required for combining two transmission paths in each case can be entered in the transmission frame to be transmitted.
- a combination point counter KPZ is inserted into the respective transmission frame and set to the counter value 0 at the beginning of each information transmission.
- the information INF encoded specifically for the mobile radio network is located in a transmission frame which contains an ATM-IC information cell formed according to the asynchronous transfer mode (ATM) is.
- ATM asynchronous transfer mode
- each ATM information cell ATM-IC has a header field of 5 bytes in length and an information field (PayLoad) of 48 bytes in length.
- PayLoad information field
- the information transmission capacity in the ATM information cell is only slightly reduced by the newly recorded information KPZ, m (4 bits of 48 information bytes).
- the information INF coded specifically for the mobile radio network, the combination point counter KPZ and the information about the total number m of the combination points can also be transmitted in information blocks according to a synchronous or plesiochronous transfer mode (SDH or PDH).
- SDH or PDH synchronous or plesiochronous transfer mode
- the radio subscriber station MS uses two redundant transmission paths to the radio devices
- Control device forwarded to BSC.
- the radio device BTS ′′ sends the information received in the corresponding transmission frame to the control device BSC via the third transmission path.
- the identical information arriving on the two transmission paths is brought together at a combination point CP1 in the control device BSC.
- the number of the two incoming transmission frames have already passed through combination points such that the current counter values of the combination point counters KPZ are added to the transmission frame and the counter value resulting from the addition is increased by one.
- the switching device LE the two individual transmission paths, which were set up by the control devices BSC and BSC, are combined at a combination point CP2.
- the information contained in the two incoming transmission frames is in turn combined and entered in an outgoing transmission frame, which is sent out by the switching device LE on a single connection path.
- IWP Interworking Point
- the control device BSC When a redundant transmission path is removed, the only combination point CP1 is present, which is arranged in the control device BSC and selected as the new transition point according to the method according to the invention.
- the control device BSC When a further redundant transmission path is added, which is set up to form a radio device (not shown), the control device BSC also combines two transmission paths at a combination point.
- the combination point CP2 located in the switching device LE is still selected as the transition point IWP in the transmission network, since the total number m of a total of three combination points passed through is recognized there by the method according to the invention.
